Dvořákovy přednášky

Vladimír Dvořák

Vladimír Dvořák (1934–2007)

Významný český vědec, který pracoval ve fyzice pevných látek. Zabýval se teorií feroelektrických látek a strukturálních fázových přechodů. Celý svůj produktivní život spojil s Fyzikálním ústavem. Byl jeho ředitelem v letech 1993-2001. Členem Učené společnosti byl od r. 1995. Byl protagonistou revolučních reforem ve Fyzikálním ústavu po roce 1989. K uctění této osobnosti a jeho práce organizuje Fyzikální ústav každoročně slavnostní Dvořákovu přednášku, přednesenou mezinárodně uznávanou autoritou v některém z oborů výzkumu Fyzikálního ústavu.

4. Graphene Ten Years Later

St, 06/06/2012 - 15:00 - 16:30

Prof. Allan H. MacDonald (University of Texas at Austin, USA)

Graphene is an atomically two-dimensional material which was first isolated for electronic property studies by Novoselov, Geim and collaborators from the University of Manchester about ten years ago. It is a gapless semiconductor formed entirely from carbon atoms and can be viewed as a giant aromatic molecule. Graphene’s honeycomb lattice structure is bipartite; atoms on one sublattice have three nearest neighbors all on the other sublattice.

3. Superfluid Helium-3: From very low Temperatures to the Big Bang

St, 08/06/2011 - 15:00 - 17:00

Prof. Dieter Vollhardt (University of Augsburg, Germany)

Since their discovery in 1971 the superfluid phases of Helium-3 have proved to be the ideal testing ground for many fundamental concepts of modern physics.

2. Quantum Information and the Foundations of Quantum Mechanics

St, 23/06/2010 - 15:00 - 17:00

Prof. Anton Zeilinger (University of Vienna, Austria)

Research on the foundations of quantum mechanics has given rise to the field of quantum information science. It should be stressed that this research beginning around the 1970s was not motivated by search for applications but rather by pure fundamental curiosity. Today, quantum computation, quantum teleportation, quantum communication, or quantum cryptography are novel concepts in information technology with no classical parallel.

1. Thermodynamic Approach to Nano-Inhomogeneous Ferroelectrics

St, 10/06/2009 - 15:00 - 18:00

Prof. Yoshihiro Ishibashi (Nagoya University, Japan)

Collaboration with Vladimir Dvorak started when he stayed in Nagoya for three months in 1975, and lasted until his final days. His visit to Nagoya gave me big stimuli and benefi ts. I could learn how to apply the group theory to phase transitions directly from him, and since then we could jointly make a certain contribution to the progress of the theory of ferroelectric phase transitions. Among our joint works, the most memorable one is the development of the theory of the incommensurate phase transitions, of which much was not known at that time.
